244-acre lake near Ontario. The lake tops out around 75 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Brook Trout fishing at Island Lake
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. In summer the feeding windows fall in early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
